WebbRTG4 PLLs can experience loss of lock at high temperature after being initialized, via device power-up or PLL reset, at cold temperature. Once loss of lock happens, the PLL lock can be recovered by issuing a reset to the PLL. The root cause of the PLL loss of lock has been identified. During RTG4 PLL initialization, a VCO gain setting is
